Name a Canadian international treaty or agreement that influences trade, with tariff and dispute mechanisms.

• A. NAFTA/USMCA (CUSMA) or WTO agreements
• B. The Kyoto Protocol
• C. The Paris Agreement
• D. The Maastricht Treaty

Answer: (A)

Understanding how trade agreements govern tariffs and dispute resolution is key here. A treaty that directly involves Canada in trade, with explicit tariff terms and a formal way to settle disagreements, fits this best. Canada’s participation in NAFTA/USMCA (CUSMA) provides negotiated tariff rules among member countries and a structured dispute-resolution process to enforce commitments when trade issues arise. The World Trade Organization agreements also fit because they establish binding tariff rules and a multilateral dispute-settlement system that member countries, including Canada, use to resolve trade disputes.

The other options address climate policy or European integration rather than trade rules and tariff mechanisms, so they don’t match the focus of the question.
